Girls, hello everyone. My restless baby has suddenly changed, he's been sleeping a lot more. I can't even get him to wake up, he falls asleep on his own without any reason. And my breasts aren't taking well, I suspect it's gas and colic. Nothing has changed in his behavior when he's awake, just a little calmer now, maybe still not clear. Deep down, I'm anxious. Has anyone ever dealt with this?
